Lubrication Device VSL8 Introduction

There are four outlet feeding ports of VSL4-KR of two line metering device, inlet ports are connected with supplying oil pipes, lubricant is transferred and powered by a lubrication pump. The change-over valve connects main line to the lubrication pump, thus pressurizing the lubricant in this main line. The control piston moves in the direction of channel near the indicator, displacing the lubricant ahead of the control piston into the relieved main line.

When the control piston uncovers the connecting passage, lubricant is transferred to the left end of the dispensing piston and displaces it to the right in the direction of channel in the vicinity of indicator. The lubricant ahead of the dispensing piston is transferred via the connecting passage to the lubrication point. With the dispensing piston in its terminal position, the pressure in main line will continue to rise to reach the preset change-over pressure of the two-line system. At this stage, the change-over valve will once again cause a pressure changing-over in main lines and the cycle will be repeated as described in stage, then two line metering device VSL4-KR finishes the completed working cycle.

Two Line Metering Device VSL4 Working Operation Graphic

Pressurized lubricant is supplied to the metering device via main line I. The control piston (1) starts moving in the direction of arrow A, displacing the lubricant in front of the control piston into the relieved main line II.

When the control piston (1) uncovers the connecting passage (2) lubricant is transferred to the right end of the dispensing piston (3), thereby displacing it to the left in the direction of arrow A.
The lubricant volume ahead of the dispensing piston is transferred via the connection passage (4) to the lubrication point. With the dispensing piston in its terminal position, the pressure in main line I will continue to rise to reach the preset change-over pressure of the two-line system. At this stage,the change-over valve of the system operates to connect main line I which has so far been under pressure to the lubricant reservoir of the lubrication pump.

At the same time the change-over valve connects main line II to the lubrication pump, thus pressurizing the lubricant in this main line. The control piston (1) moves in the direction of arrow B, displacing the lubricant ahead of the control piston into the relieved main line I.

When the control piston (1) uncovers the connecting passage (5) lubricant is transferred to the left end of the dispensing piston (3) and displaces it to the right in the direction of arrow B. The lubricant ahead of the dispensing piston (3) is transferred via the connecting passage (6) to the lubrication point. With the dispensing piston (3) in its terminal position, the pressure in main line II will continue to rise to reach the preset changeover pressure of the two-line system. At this stage, the change-over valve will once again cause a pressure changing-over in main lines I and II and the cycle will be repeated as described in stage 1.

Two Line Metering Device VSL4 Output Volume Adjustment

Variation KR of two line metering device VSL4 for infinitely variable adjustment and visual indication.Infinitely variable adjustment of lubricant output is achieved by turning the adjustment screw F. Maximum output is available if the lock screw E and the adjustment screw F are in their uppermost position. By turning the screw downward the output can be continuously reduced. With the two screws in their fully closed position, the indicator pin G is completely restrained and, because the pin is attached directly to the dispensing piston, the lubricant output will be nearly zero. The indicator pin shows the correct functioning of a pair of outlets. After setting the lubricant output, the adjustment screw F will be locked in position by means of screw E. To secure the setting, lock the adjusting screw only when the indicator pin is retracted.
